A new beta for the Dropbox desktop sync software was just released and one of the included new features is the ability to import photos straight from your iPhoto library. The software is smart enough to make folders out of your albums and events, so your photos will be just as organized in Dropbox as they are on in iPhoto.
Well, that would make moving to Dropbox from iPhoto easier for most users.
